T 0 all whom it may concern:

Be it known that 1, JOHN A. DE Vrunss, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Educational Devices, of which the following is a full, clear,

.is a cross sectional view of the sphericalshaped member; and Fig. 3 is an elevation of one of the semi-s herical-shaped shells which forms one-half ol said member.-

This invention relates to educational devices, and particularly to devices that are used in instructing scholars in geography.

' The main object of my invention is to provide a device that will permanently impress upon a pupils memory the relative position of (places upon the earth in a more graphic an real manner than was teaching geography.

Briefly stated, my invention consists in a provided on its (no terior with a partially com ileted map of the world consisting of the outlines of the continents, or lines or marks indicating where the outlines should be drawn, said map being ada ted to be completed by a pupil who fills in t 1e details such for example, as the colors used for the different States and countries, the symbols used to designate the cities and other features and the names of same, thereby Pproduciug a geographical globe referably, the spherical-shaped member is composed of two semhsplicrical-slraped shells sothat the pupil can handle the same easili while filling in or completing the map, said shells being adapted to be connected together afterthe details of the map have been filled in so as to form a complete geographical globe which can be mounted on a stand or support. 7

Referring to the drawings which illustrate the preferred form of my invention, 1 and 2 designate two sen1i-spherical-shaped shells. These shells may be formed of sheet metal, cardboard, papiornnache, or any other suitable material, and on the exterior of some, the continents of the earth are outlined,

either by embossing or impressing the matenossible with the devices which have heretofore been used in rial from which the shells are formed, or by printing or ainting the outline of the oontinents. I a so prefer to print, emboss, or impress the parallels and meridians and the rivers and mountains of each continent so that the pupil can complete the map by fillingin the boundary lines of the States and countries and coloring same and also printing the names and symbols which designate the cities, rivers, lakes, States, lands, etc. The pupil places each section of the spherical-shaped member on his desk while he is working on same so that he can handle it easier than if the sections were connected together and mounted on a stand or support. One of the shells is provided adjacent its edge with yielding clips 3 that are secured to the inside of said shell, as shown in Fig. 2, so that when the two shells are placed together, said clips ,will engage the inside mountains, is-

face of the edge portion of the other shell and thus hold said shells together. It is also preferable to provide one of the shells with a strip or band 4 containing gum or mucilag'e so that it will adhere to the other shell and thus permanently secure said shells together. Each shell is provided with an opening 5,. as shown in Fig. 2, and after the shells have been connected together, the sphericalshaped member mounted on a staml 6 provided with a support 7 which passes through the openings 5 in said shells so that the globe can be revolved or turned about the support 7 as an axis. it is immaterial, however, so far as my broad idea is comerued, how the shells are connected together or what the globe mounted on as my invention, broadly stated, consists in a egcographi globe that is only partly formed and whic is adapted to he completed by filling: in the colors, names and symbols that are generally used on maps to designate the various features thereof. lns'toad of providing the spherical shaped member with the complete outlines of the continents and islands, as shown in Fig. 1, said member can be provided with dots or marks indicating where the outlines of the continents and islands are to be drawn, as shown in Fig. 3. l urthermore, instead of printing or embossing the mountains and rivers, as heroin shown, the points where same should appear can be indicated by marks or in an other writable manner. in fact, the degree of compleiou of i e map which is formed on. the splierii-aie:hapml member before is given. to tho umil, will.

depend upon the extent of the pupils knowledge of geography. classes it is preferable to have the globe or spherical-shaped member provided with the complete outlines of the continents, islands, mountains, rivers, etc., while for advanced classes, the globe can be merely provided with marks or other devices indicating Where the outlines of the continents, mountains, etc., are to be drawn. This method of mak ing maps impresses more forcibly upon a fipupils mindthe relative location of the di 'erent places on the earth than if the map were made on a flat surface as is the usual custom.

As the globe is very inexpensive to manufacture, a pupil can obtain one at a low cost and then complete it .in the manner described,

. thus obtaining a geographical globe containing a complete map of the world.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent is: I

l. A globe for use as an educational device, comprising two semi-spherical shells, means on the edge of one of them to detachably engage the inside of the edge of the For primary grades or r tachably secure said sections together and 40 means to permanently secure them together,

.each section having a plane edge whereby it can rest ona table while the map is being filled in, and then be joined permanently into a globe.

In testimony whereof I hereunto affix my signature in the presence of two witnesses, this twenty seventh day of September 1907.

JOHN A. DE VILBISS.'.
